Is there going to be a group buy coming up? Also what does the +200 Nav, Voice + VIM mean? My car is currently coded with VIM and it has navi what does that option do for me?

This means activation of Nav, Voice and ViM. If you already have these activated, then you do not need this option. If you need more info, please send me an email to info@bimmerretrofit.com with your VIN # and I will be happy to help you.
